Lindelof's Theorem
The Surface of Revolution generated by the external Catenary between a fixed point 
and its conjugate on theEnvelope of the Catenary through the fixed point is equal in Area to the surface of revolution generated byits two Lindelof Tangents, which cross the axis of rotation at the point and are calculable fromthe position of the points and Catenary.
